Cardas Neutral Ref ICs time to change??

I have used Cardas Neutral Reference ICs for about 8 years between various CD players and integrated amps or power-pre amps. Right now it is a Sony SCD XA 777ES and an Exposure 2010S. I find the Cardas to be very detailed and clear but in the times I have tried other IC cables I have found that the others (Analysis plus, Audioquest ect) tend to have bigger stages and more HF extention with slightly more fullness in the bass. and not sound as mechanical. I do always end up sticking with the Cardas and I am not sure why. Opinions on the Cardas NR IC would help. Thanks,keith
